Could not resolve plugin artifact 'com.google.cloud.tools:appengine-gradle-plugin: 2.4.1

[R. de Wilde]

Is the plugin no longer available thru the gradlePluginPortal?

I can't find it com.google.cloud.tools:appengine-gradle-plugin listed:
https://plugins.gradle.org/m2/com/google/cloud/tools/

[Chanseok Oh]

Check this doc to understand how to apply the plugin. It may be that the way the plugin should be applied changed at some point?

Nah, I did just that. It seems to be available on mavenCentral, but not sure why my script produces an error.
https://search.maven.org/artifact/com.google.cloud.tools/appengine-gradle-plugin/2.4.1/jar

It is a Kotlin MPP project, so maybe this does somehow change the structure.

In my settings.gradle.kts in the root I have this:

pluginManagement {
    repositories {
        gradlePluginPortal()
        mavenCentral()
        maven(url = "https://maven.pkg.jetbrains.space/public/p/compose/dev")
    }

    resolutionStrategy {
        eachPlugin {
            if (requested.id.id.startsWith("com.google.cloud.tools.appengine")) {
                useModule("com.google.cloud.tools:appengine-gradle-plugin:${requested.version}")
            }
        }
    }

}

In the root build.gradle.kts I added this:

plugins {
    // ... other stuff
    id("com.google.cloud.tools.appengine") version " 2.4.1" apply false
}

and this:

buildscript {
    repositories {
        // ... others
        mavenCentral()
    }
    dependencies {
        // ... others
        classpath("com.google.cloud.tools:appengine-gradle-plugin:2.4.1")
    }
}

In the subproject backend I added this:

plugins {
    // ... other stuff
    id("com.google.cloud.tools.appengine")
}

The error seems to suggest, that it did search the MavenRepo/central:

org.gradle.internal.exceptions.LocationAwareException: Build file '/Users/Robert/StudioProjects/mercado/build.gradle.kts' line: 1
Plugin [id: 'com.google.cloud.tools.appengine', version: ' 2.4.1', artifact: 'com.google.cloud.tools:appengine-gradle-plugin: 2.4.1', apply: false] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'com.google.cloud.tools:appengine-gradle-plugin: 2.4.1')
  Searched in the following repositories:
    Gradle Central Plugin Repository
    MavenRepo // Here <<<<<<
    maven(https://maven.pkg.jetbrains.space/public/p/compose/dev)

Anything else I am missing? I did not add anything to allprojects-block, nor to the buildSrc-dir

Oh shit. There was a space before my version number, so like " 2.4.1" 😭

Sorry to bother, thanks for your help
